Sorry for not mentioning it here. With kernel 3.16 process accounting worked
nicely. We do not have any data on the exact kernel version where it started
to fail. I do see these issues since quite a while, but I was never sure
whether it was an issue in atop or the kernel and I do not recall on what
exact combination of atop + kernel version it failed to work.
As an additional notice: The mail addresses of Balbir and Shailabh which I got
from source code annotations of taskstats.c and getdelays.c do not work
anymore.
